Abstract

The invention provides an electroacoustic device and mobile terminal. A plurality of sound absorption cavities are arranged in a box body of the electroacoustic device, sound absorption materials are filled in the sound absorption cavities, thus according to design requirements, through change of the type or particle size of or different filling amount of the sound absorption materials filled in each of the sound absorption cavities, combination of different types and different particle sizes or different filling amount of sound absorption materials in the electroacoustic device can be flexibly realized, and a relatively good sound production effect of the electroacoustic device is easily realized.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to an electroacoustic device and a mobile terminal. Background technique [0002] At present, in mobile terminal products, in order to enhance the bass effect of the electro-acoustic device, it is generally necessary to set up a sound-absorbing cavity in the electro-acoustic device, and fill the sound-absorbing cavity with sound-absorbing particles. Absorption effect, get better bass effect. In the prior art, the sound-absorbing material is packaged and the packaged sound-absorbing material is assembled in the sound cavity. In this case, the structure of the sound cavity is single, resulting in poor sound-absorbing effect and poor user experience. Contents of the invention [0003] The invention provides an electroacoustic device and a mobile terminal that improve user experience. [0004] The invention provides an electro-acoustic device, the electro-acoustic device includes...
